rnnnnn LOOM.

Application filed July 3, 1919. Sierial No. 308,385.

To all 10 720% it may concern:

Be it known that 1, Jonas Nonrrrnor, a citizen of the United States,residing at Hopedale. in the county of Worcester and State ofMassachusetts. have invented certain new and useful Improvements inFeeler Looms; and I do hereby declare the following to he a full. clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in feeler looms and moreparticularly to an improvement in bobbin chutes therefor.

Feeler looms are a type of weft replenishing looms wherein the weftreplenishing mechanism operates to insert a fresh supply of fillinginthe active shuttle when the old filling is exhausted to apredeterminedextent. as determined by the filling feeler mechanism.These looms are usually constructed with the weft replenishinginechanismlocated on one side of the loom and the filling feeler mechanism locatedon the other side of the loom. Upon the indication of critical orpredetermined exhaustion of the filling by the filling; feelermechanism, the weft replenishingoperation takes place upon the nextsucceedinobeataipof the lay. At this time the usual thread partermechanism is thrown into operation to sever the filling end extending;fromthe selvage to the bobbin. hen the exhausted bobbin is eiccted fromthe shuttle it strikesa bobbin chute and is deflected into a receptacle;The bobbin chute usually consists of an apron mounted upon the lay orupon the frame of the loom and serves only the purpose of deflecting theexhausted bobbin.

The present invention .has for an object to provide a bobbin chute whichis mounted in a novel manner. and which may be readilv applied to anyloom and particularly those which are already constructed and inoperation without changing the construction thereof. The invention hasfor another ohiect to provide a bobbin chute which, in addition to itsfunctions as a bobbin chute, serves as a thread extracting device. whichwill engage the outgoing filling: end as the lay beats backward upon thefirst pick of the shuttle 'after replenishment, and hold the filling sothat as the shuttle travels onward, its movement causes the filling tohe pulled.

' therewith.

through the shuttle eye. To the accomplishment of these objects and suchother objects as may appear, the invention consists in the structurehereinafter described andclaimed.

In the drawing which illustrates the preferred embodiment of theinvention Fig. 1 is a sectional elevation of a portion of a feeler loomshowing the improved bobbin chute and parts immediately associated Fig.2 is a section on line 22 Fig. 1 viewed in the direction of the arrows.v The improved bobbin chute indicated generally by 10 consists of anapron 11, preferably of metal, and which is pivoted on the pintle 12,supported by a bracket 13 carried by a receptacle 14 and secured theretoby bolts 15, I

The receptacle 14 may be any receptacle employed to receive theexhausted bobbins when the replenishing operation occurs, and

is in the present instance shown as a metallic receptacle rectangular incross section and having a cut away portion as shown in Fig. 1, which isdesigned to permit the receptacle to fit under the ordinary type ofstationary bobbin chute. -The ltiracketlfi is of substantialconstruction and is preferably cast in such a form as to supply the cutaway portion of thereceptacle It, so that in reality a receptacle isformed which has a substantiallv uniform height ofwall on all sides. Thebracket 13 is provided with ears 16 adapted to fit over the rim portion17 of the ordinary bobbin receptacle and is also provided with alugr 18having: slots 19 -i'l1816]11 which are adapted to'fit over heads :20 ofarms 21. The arms 21 are fastened to a portion 22 of the frame of theloom by the bracket 23 and bolt 2d. The receptacle 14 rests upon thefloor as shown in Fig. 1 and its position under the loom is regulated bythe length of the arms 21 so that the bobbin chute 1O inclines up underthe shuttle box 25. In this position when the lay 26 is at the extremeforward point of its heat, and when replenishment occurs, the ex haustedbobbin falls from the shuttle box 25, strikes the apron 11 of the bobbinchute and is deflected into the receptacle '14.

The apron 11 is y'ieldingly held in the position shown in Fig. 1 by acoil spring 27 having one end 28 thereof bearing against the frontsurface of the apron 11 and the other end 29 against the bracket 13. It

sometimes happens that an exhausted bobbin is caught between the bobbinchute and the lay and should this occur the apron 11 is permitted toswing 'lforwardly. about the pintle 12, so that no dam: e can occur andno parts .be broken and v the bobbin has freed itself, the apron 11 isreturned to its normal operating position by the spring 27.

It will be observed that the bobbin chute 10 can be directly mountedupon any receptacle without the use of the bracket 13 and in the drawinga receptacle of the ordinary construction for receiving exhaustedbobbins is shown but obviously a receptacle of any desired shape couldbe used, the only requisite being that when the bobbin chute andreceptacle are placed in an operative position, that the bobbin chuteshould extend up under the shuttle box'so that it willsuccessfully'operate to-d'etlect a falling bobbin into the receptacle.

lVhen replenishment is indicated, the usual thread parter operates tosever the filling end extending to the selvage at a point. near theshuttle, and in the ordinary constructionot ieeler loom, the severed endis pulled through the shuttle eye by the ejected bobbin as it falls intothe receptacle. Occasionally, and in fact frequently, it happens thatthis filling end is caught between the shuttle and the binder or thefront wall of the shuttle box, and is held thereby, so that, as theejected bobbin falls it doesnot pull the filling end through the shuttleeye. \Vhen the shuttle starts on its flight on the first pick a'l'terreplenishment it often draws the filling end toward and sometimes intothe shed where, if it is allowed to remain, there results a double pickand consequent blemish in the cloth.

aware were mounted on either the lay or upon a part of the loom frame.These devices operate with more or less uncertainty depending on thechance of the filling end coming into engagement therewith.

in order to eliminate the uncertainty of operation of the threadextracting device, I have provided the bobbin chute 10 with a series ofteeth or engaging devices 30. It will be observed that when the laystarts to beat back, and before the shuttle is started on its first pickof the replenishment, that the filling end extending from the ejectedbobbin up through the eye of the shuttle is drawn directly across themouths of the engaging devices 30, so that when the shuttle starts onits flight the filling end is engaged thereby so that further movementof the shuttle arts to pull the filling end through the delivery eye andprevents the formation of double picks.

I believe that I am the first to provide a bobbin chute which does notmove with the,

lay, with thread extracting means, so that as the lay moves backward thefilling is drawn into engagement with the thread extracting means. It isalso to be observed that the receptacle and bo'bbinchute mounted thereonform a unit which may be applied to any loom but which is particularlyadapted to be applied to looms which are already constructed, in whichcase the only adjustment needed is to regulate the length of the arm 21so that the boboin chute extends up into an operative position under theshuttle box.

I claim:

A loom having, in combination, a bobbin receptacle provided with acutaway portion, a bracket fitting into the cutaway portion and servingas a continuation of the receptacle to form with the receptacle asubstantially rectangular body, a bobbin chute yieldingly mounted uponthe bracket, and arms engaging with the bracket and adapted to beadjustably connected with the frame of the loom to maintain the bobbinchute in a definite operative position with relation to the loom.
